A new analysis of NASA satellite data shows Africa’s Congo rainforest, the second-largest tropical rainforest in the world, has undergone a large-scale decline in greenness over the past decade.

The study, led by Liming Zhou of University at Albany, State University of New York, shows between 2000 and 2012, the decline affected an increasing amount of forest area and intensified. The research, published Wednesday in Nature, is one of the most comprehensive observational studies to explore the effects of long-term drought on the Congo rainforest using several independent satellite sensors.

Using an innovative satellite technique, NASA scientists have determined that a previously unmapped type of wildfire in the Amazon rainforest is responsible for destroying several times more forest than has been lost through deforestation in recent years.

In the southern Amazon rainforest, fires below the forest treetops, or “understory fires,” have been hidden from view from NASA satellites that detect actively burning fires. The new method has now led to the first regional estimate of understory fire damages across the southern Amazon. (more…)

Development in Brazil: Double cropping helps Brazil’s development

It’s not just about agriculture. Growing two crops a year in the same field improves schools, helps advance public sanitation, raises median income, and creates jobs.

PROVIDENCE, R.I. [Brown University] — New research finds that double cropping — planting two crops in a field in the same year — is associated with positive signs of economic development for rural Brazilians.

The research focused the state of Mato Grosso, the epicenter of an agricultural revolution that has made Brazil one of the world’s top producers of soybeans, corn, cotton, and other staple crops. That Brazil has become an agricultural powerhouse over the last decade or so is clear. What has been less clear is who is reaping the economic rewards of that agricultural intensification — average Brazilians or wealthy landowners and outside investors. (more…)

Eyjafjallajökull. While some say it is “unpronounceable”, it would be a good idea to get used to the name because for sure it is going to be around the international media for a long time to come.
